[0047] Combine the following Figure 1-3 To illustrate the control logic of the steam module of this embodiment;

[0048] refer to Figure 1-3 After the water cup assembly 2 is filled with water, the steam module receives a start command from the control panel of the dishwasher, and the heating pipe 312 of the steam assembly 3 is powered on to start heating. One second later, the water pump assembly 4 is powered on to start water intake for one second. During this process, the temperature sensor 314 detects the temperature of the heat transfer plate 313 of the steam assembly 31. It can be seen that by first controlling the heating pipe 312 to be powered on to start heating for one second, and then controlling the water pump assembly 4 to be powered on to start water intake for one second, the steam assembly 3 can quickly generate high-temperature steam when the water pump assembly 4 pumps water.

[0049] When the temperature displayed on the panel of the dishwasher is less than 80°C, the heating tube 312 operates at 80% power. This is mainly to avoid excessive temperature difference between the actual temperature of the heat transfer plate 313 and the temperature displayed on the panel due to the transmission rate, thereby protecting the steam component 3 and reducing energy consumption.

[0050] When the temperature displayed on the panel of the dishwasher is greater than 80°C, the heating tube 312 runs at full power and does not pause until the end of the program. During this period, the water pump component 4 works for 1 second and pauses for 18 seconds according to the water intake, and continuously cycles until the end of the program to achieve continuous output of high-temperature steam to meet the steam requirements of each mode stage of "washing-disinfection-drying" in the dishwasher, thereby improving the dishwasher's cleaning index, drying index, disinfection efficiency and other performance, achieving the effect of reducing energy efficiency and washing time.

[0051] When the panel displays a temperature greater than 135°C and is detected twice, the control board automatically increases the water inlet time by 0.5 seconds, and can be increased up to 2 times, i.e. 1 second, to prevent misjudgment.

[0052] When the steam module receives the stop command from the control board, the heating pipe stops heating immediately, the control board program is reset, the water inlet time of the water pump component 4 is restored to 1 second, and waits for the next cycle. It can be seen that by controlling the water inlet time of the water pump component 4 to return to 1 second before shutting down after the heating pipe stops heating, the steam component 3 is effectively prevented from drying out.

[0053] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
